LEWIS GREVELING, OF AKRON, OHIO, ASSIGNOR TO IIOW'ES & EXVELL, OF SILVER GREEK, NE\V YORK.

FLOUR-PACKER.

SPECIFICATION forming part of Letters Patent No. 310,496, dated January 6, 1885.

Application filed October 2.), 1884. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS OREVELING, of Akron, in the county of Summit and State of Ohio, have invented new and useful Improve 5 ments in Flour-Packers, of which the following is a specification.

This invention relates to an improvement in that class of flour-packers which are provided with a packing-tube into which the flour is de- 1c livered from the bin, and in which a revolving auger operates, which forces the flour into the barrel, bag, or other receptacle placed upon a movable platform. The latter recedes from the packing'tube gradually during the opera- 1 5 tion of packing as the barrel or bag becomes filled. The platform is suspended from a rotary shaft by means of chains or ropes, and the shaft-is provided with a brake and acompensating-spring, whereby the necessary resistance is produced in the platform to properly pack the flour, bran, or other material.

The object of my invention is to provide the packer with a simple and durable compensating-spring; also to improve the brake which is applied to the platform-shaft, and also to pre vent the platform from binding in moving up and down between the'posts of the frame.

To these ends my invention consists of the improvements in the construction of the pack- 0 er, which wilt be hereinafter fully set forth,

and pointed out in the claims.

In the accompanying drawings, Figurel is a side elemtion of a flour-packer provided with my improvements. Fig. 2 is a horizontal see- Fig. 3 is a side elevation, on an enlarged scale, of the brake mechanism. Fig. I is avertical section in line y y, Fig. 3. Fig. 5 is a fragmentary sectional elevation of the platform and supportingchains.

Like letters of reference refer to like parts in the several figures.

A A represent the upright front posts, and A A the rear posts, of the packer-frame. B is the flour-hopper, and B the packing-tube at the lower end thereof. 0 is the movable platform, and c the horizontal shaft, to which the platform is connected by chains or ropes d. The platform is provided with standards E, which slide between the posts A A on both sides of the machine. The shaft cis arranged in rear of the packer-tube, and the chains connecting the platform with the shaft 0 run ordinarily from the platform to the shaft in rear of the tube B. The packingauger exerts a pressure upon the front part of the platform 5 5 in packing, and as the platform is ordinarily supported by the chains at a considerable dis tance in rear of the vertical line in which the packing'auger operates upon the platform, the platform receives by this pressure a tendency to tilt, which causes the platform to bind in its ways as it is forced down by the packingauger. In order to avoid this, I attach guidepulleys e to the front posts, A, in such a position as to retain the chains parallel with the axis of the packer-tube, on both sides of the latter, so that the pressure of the spring will act upon the platform, through the medium of these chains, in lines parallel with the ways in which the platform moves and in the same ver- 7c tical plane and with the packingauger,whereby the binding of the platform in its ways is prevented and a more satisfactory action of the brake and compensating-spring is insured.

F represents a coiled spring arranged ver- 7 5 tically on one side of the packer-frame, and connected at its lower end to the latter, while its upper end is connected by a rope, cord, or chain, f, to the platform-shaft c. The rope f runs from the spring I upwardly around a guidepulley, G, attached to the upper portion of the packerframe, and then downward 1y to the shaft 0. I prefer to attach the rope f to the shaft 0 by means of a sleeve or pulley,

H, which is seen red to one end of the shaft 0. The rope is preferably attached to the spring F by means of a chain, I, and hooks it, so that the tension of the spring can be increased or reduced by shortening or lengthening the chain.

K represents the brake-pulley secured to one end of the shaft 0, and 7c is the brake-band surrounding the upper portion of said pulley.

L L are short levers pivoted to the posts A A below the pulley K, and connected with 5 both ends of the brake-band.

M represents the weighted brake-lever, and m a rod or link connecting the short arm of the brake-lever with the levers L L. By raising the long arm of the brake-lever M both ends of the brake-band are raised simultaneously, thereby lifting the brake-band entirely from the brake-pulley at once, and preventing the brake-band from dragging on the brake-pulley, which occurs when only one end of the rake-band is moved by the brake-lever.

I claim as my invention 1. In a flour-packer, the combination, with tlie movable platform and the shaft to which the platform is attached, of a coiled spring, F, and a connecting device, substantially as described, whereby said spring is connected with said shaft, substantially as set forth.

2. In a flour-packer, the combination, with the movable platform and the shaft to which the platform is attached, of a pulley, I-I, mounted on said shaft, a coiled spring, F, and a cord, f, connecting said spring with said pulley,sub-

stantially as set forth.

3. In a fiour-packer, the combination, with the stationary frame, the movable platform,

20 and the shaft to which the platform is attached,

of a coiled spring, F, and an adjusting device,

substantially as described, whereby the coiled spring is attached to the frame, substantially as set forth.

4. I11 a flour-packer, the combination, with the stationary frame, movable platform, and shaft 0, of the guide-rollers 0, attached to said frame, and chains d, connecting the platform with said shaft and running over the rollers e, substantially as set forth.

5. In a flour-packer, the combination, with a movable platform and the shaft 0, of the brake-pulley K, brake-band 7c, levers L L, connected with both ends of the brake-band, and a weighted lever, M, whereby both ends of the brakeband are simultaneously moved, substantially as set forth.

itness my hand this 24th day of October, 1884.
